LLLT shifts up the O2•- generation in PMN. O2•- generation determined by SOD-inhibitable reduction of cytochrome c for Control and Laser groups. Human PMN were irradiated with 660 nm or 780 nm laser light; p < 0.01 (*) between PMN irradiated with laser 660 nm and non-irradiated PMN; p < 0.01 (*) between PMN irradiated with laser 780 nm and non-irradiated PMN; p < 0.01 (*) between PMN irradiated with 660 nm and PMN irradiated with 660 nm along with SOD; p < 0.01 (*) between PMN irradiated with 780 nm and PMN irradiated with 780 nm and SOD. Irradiated and non-irradiated PMN stimulated by fMLP showed no statistically differences between them (p > 0.05). Irradiated and non-irradiated PMN stimulated by C. albicans showed no statistically differences between them (p > 0.05). Results represent means ± standard deviations. p value obtained with ANOVA followed by Tukey test (level of significance of 5%). fMLP, N-Formyl-methionyl-leucyl-phenylalanine; SOD, superoxide dismutase.
